To all 'whom i may oo'ncem: I f

Be it known that I, CImnLi-:s H. 71n- LiAMs, J r.,a citizen of the United States, residing at the city of Chic-ago, State of Illinois, ave invented a certain new and useful Improvement in Brake Beam Third loint- Suspension Mounts, of which the following is a full, clear, and exact description, Asuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming cation, in which- Figure 1 is a plan view of one form ot' my improved brake beam third point suspen` sion. Fig. 2 is an enlarged vertical scetional view on line 2 2 of Fig. l. Fig. 3 is a plan view of another modified form ot' suspension spring mounting. Fig. 4'is a vertical sectional view on line 4-1 of Fig. il. Fig. 5 is a plan view. of another form of sus pension spring mounting. Figl 6 is a vertical sectionalview on line (3J-6 ot' Fig. Figs. 7 and 8 are plan views of other modified forms of suspension spring mountings.

This invention relatesto a new and usct'ul improvement in brake beam third point suspension-spring mountings, its object being toenable the suspension spring to be swung part of this specifi-A out of the way of the brake beam in the 'eventthat it is desired to anhang said beam.

In Patent No. 997,888 granted to me July 11, 1911, is shown an arrangement ot third point suspension spring wherein the same is ixedly mounted to the spring plank of the truck`. Being located under the brake beam,

it is necessary in the patent referred to, especially where the beams are hung from trucks having narrow 'wheel bases, topmanipulatc the beam and twist itv around in close quarters Where it is desired to anhang and remove the beam or to rchaug a new beam. The third point suspension spring being located directly under the beam is in the way and sometnn'esit4 is desirable to either remove this third point suspension spring to permit the unhanging of the beam and the rehauging of the new beam, orto swing said third pointJ suspension spring to one side to enable tbc removal and replacement ot' the beam,

-My 'ncsent invention contemplates means for enabling the third point suspension itsl pivot bolt.

removed entirely to permit the unhanging and rehanging of beams in the truck.

In the drawings l indicates the Y spring plank of an ordinary ear truck shown as be'- in g inthe form of-a channel and 2 indicates the third point suspension spring for the brake beam.

spring to be swung out of the-way or to bie*- 3 indicates a pivot bolt shown in Figsfl i Wlan loosened these hook bolts permit the suspension spring to be swung on the'piv'ot, bolt 3 for purposes above indicated.

In Figs., 3 and ,4, I haveA shown another form in which oppositely disposed clam ing plates 5 are employed, the ends of ese plaies which are spaced from the spring. plank 2 being secured in'position by bolts (i.

When these bolts are removed the third point suspension spring can beswung on as indicated 1n dotted lines, Fig. i

In Figs. 5 and (S, I' have shown another modieation in which the clamping plates 7 are. provided with lips designed to hold the third point suspension spring in place. When it is desired to swing the spring on pivot bolt the bolts 8 may be loosened.

in Fig. 7. l have shown another modification in which the third point suspension spring is divided into two sections, Q and Q, each of Which sections is secured in position by the bolt 3, the ends being held under the spring plank by means of a U'shaped clamping plate. Upon the removal of the bolts 3 the desired `spring section may be.- ren'xoved.l

In Fig. 8 l have. shown anothei; modifiea-- tion in which there is a clainping plate 9 similar to the clamping plate shown in Fig. il, land a slotted platel() whiehiwhen its holding bolt 1l ls loosened, permits said en with :L part; of u cnr ai p0 e: "mn 55mm@ 10 maven?.
